"How can you let him go?" Dick demanded angrily as he glared at Gordon.

"Dick, things like that happen all the time. I know it must seem unfair…"

"That's why we have Batman." Dick snapped. "You can't cut a deal with guys like Tony Zucco. They stay behind bars until they draw their last breath and then you burn the jail to the ground and bury them under the rubble." Dick turned around to face a young man, who heard every sentence Dick said as he left the interrogation room as he glared at Dick before walking away.

"Dick, you should watch your temper." Gordon said, warning Dick.

"Who was that?" Dick growled, noticing that the man didn't like Dick.

"Nicholas Zucco. Tony's son." Gordon said.

"I can't believe you're letting the guy that killed my parents walk free…"

"He's not walking free, Dick, he will be in protective custody with his family, because of his testimony against Maronis. I know you don't like it… but he'll be under constant surveillance, no way he'll hurt anyone ever again." Gordon assured him as Dick's face turned red in anger.

Gotham City

The armored van with Tony Zucco inside was driving down the road before dense gas blinded the driver, causing for him to drive towards road railing.

"What's going on?" Zucco demanded.

"Ambush!" The driver exclaimed as the guard went out with a shotgun.

"I don't see him."

Gunshots rang out as Nightwing jumped down from above, knocking the guards out.

Zucco was in the van, panicking before Nightwing opened the door and pulled Zucco out. "What the…"

Nightwing slammed Zucco to the ground and beat him until his face was bruised and bloodied before Nightwing pinned him to the van. "Please, don't…" Zucco choked out as Nightwing grabbed him by his throat.

"How many people have begged for life before you killed them?" Nightwing growled.

"Look, whatever you want, I can give…"

"I want my parents back!" Nightwing yelled and Zucco widened his eyes in realization.

"Grayson?" Zucco paled as Nightwing squeezed his throat, strangling him.

"Give me one good reason I shouldn't end you right here, right now. One good reason!" Nightwing snarled.

"I have family too… please… I'm sorry… it wasn't personal… it was just business…" Zucco begged.

"And my parents paid their lives for it!" Nightwing shouted, beating Zucco up until his face was bloodied and then he started to break his arms and legs.

Suddenly, gunshots rang out. "Maronis." Zucco realized. "They'll kill me. Please. Don't let them…"

"No." Nightwing growled, letting Zucco go as he ascended above, watching the Maroni gangsters approach Zucco.

"You must pay for what you did, traitor." One of the mobsters said as they started to pour acid on Zucco's chest as he screamed in pain and excruciating agony.

Part of Dick enjoyed the agony Zucco was in but… then… Bruce's words echoed in his mind as he realized that his parents wouldn't want him to stoop down to Zucco's level. Nightwing descended from above as he beat up the mobsters and as he finished off the last one, he looked at unconscious Zucco, who had burned chest.

Present

"That was you?" Henry demanded.

"Jesus, Dick…" Barbara whispered, not believing that one of her closest friends and former lover would do something so horrible.

"He spent six months in a coma and then he was locked away forever." Dick remembered. "Go ahead. Judge me."

"We're not." Helena assured him.

"I thought that Nick was dead." Henry said. "After Zucco went into coma, the deal for protection was off. Most of the Zuccos were killed, wife, sons… and as far as I know, only one survived because she had changed her identity before that and went into Witness Protection. She wanted nothing to do with her old man."

"Who?" Helena asked.

"Well… it might take a while to track her down. I have to call Lyla to get on with this."

Later, Gotham Municipal Bank

"Miss Branch?" A man asked as a young woman was at the desk, doing some paperwork. "You have a client."

"Sonia Branch?" Dick asked as the woman looked up and stared in shock at seeing Dick. "I need your help."

"Jesus Christ." Sonia paled as Dick and Henry filled her in. "Nick…"

"I know it's got to be tough…"

"This is why I had left into WitPro before the shit hit the fan." Sonia grumbled.

"Look, do you know where he could be hiding? He's killed a lot of former members of Haly's." Dick pleaded.

"I don't know." Sonia said. "I swear I don't know. I cut all ties with Dad long before that and changed my name. I'm sorry about your parents, Dick, I really am. I never liked what my father was doing and I hated him for what he did to your parents as much as you did."

They all nodded. "He may try to contact you." Henry said. "If he does, call us or the cops, OK?"

Sonia nodded as Henry wrote down a phone number. "Thanks. Just one thing. Nick is very unstable and unpredictable. Whatever you're gonna do, be careful."

Elsewhere

"Why are you doing this?" Clay begged as he was restrained to a chair.

"I'm just collecting an old debt. With interests." Nicholas said as he poured acid on Clay's face as he screamed in pain.

Later

Dick went into an alley as there was police tape around the crime scene as they saw Clay's corpse on the ground with melted face.

"I'm sorry, Dick." Gordon said.

Dick knelt towards Clay as he wiped his face in sadness and tears filled his eyes.

"Dick. We need to find out who else Nick might be after." Henry said. "Come on, think."

Dick tried to think frantically, his thoughts going to any potential victims as he was trying to protect his family.

Elsewhere

Raya Vestri, Dick's childhood friend and acrobat went out from the shower, tying the bathrobe as the phone in her apartment rang and she answered it.

"Hello?" No one replied on the other side. "Is anyone there? Hello?" Raya shrugged as she hung up.

The man in the car hung up as he observed Raya through his goggles as he put his phone down, watching Raya hang up before his phone rang as he picked it up.

"Yes?"

"Nick? I don't know if you're still using this number but if you are, I know what you're doing." Sonia said. Nick didn't reply, just glaring with rage and resentment. "Just stop. They're innocent people. They did nothing to you."

"All bills come due, Sonia. Don't make me collect yours too."

"Nick!" Sonia snapped but Nick hung up before he was about to target his next victim.
